UNITED STATES PATENT OFFICE.

WILLIAM H. SADLER, OF MOLINE, ILLINOIS, ASSIGNOR ONE-HALF HIS RIGHT T()JAMES G'. WELLS, OF SAME PLACE.

. IMPROVEMENT IN CAR-COUPLINGS.

Specication forming part of Letters Patent No. 183,217, dated October10, 1876; application led August 23, 1876.

To all whom it may concern:

Be it known that I, WILLIAM H. SADLER, ot' Moline, in the county ot'Rock Island and State of Illinois, have invented certain new and usefulImprovements in Car-Couplings; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable others skilled in the art to which it appertains to make and usethe same, reference being had' to the accompanying drawings, and to thelettersl of reference marked thereon, which form apart of thisspecification.

This invention relates to improvements in railway-car couplings; and theinvention consists in certain new and improved devices and combinationsof devices, whereby the operation of coupling cars automatically isrendered more certain and effective, all as hereinafter more fully setforth.

In the accompanying drawing, Figure lis a front elevation of a draw-headembodying my Fig. 2 is a vertical sectional view in the line :n w inFig. 1. Fig. 3 is a sectional view in the same vertical plane as Fig. 2,but showing the operating parts in different positions from that shownat Fig. 2. Fig. 4 is a perspective view of the tumbler-hook.

Referring to the parts by letters, A is the draw-head, the mouth ofwhich is enlarged at its rear portion, to form a seat for thetumbler-hook B, which is pivoted therein at b. The'tumblerB is curvedand formed, as plainly shown in the drawings, with an enlarged upperend, b', which is cut into teeth b, and a smaller curved end, b'", whichforms the hook to secure the link in coupling. The hook end of thetumbler B is hinged or jointed to the main portion at 12, as moreplainly sho n at Fig. 4, so as to permit of slight exure, andotsubstituting anotherin case of breakage. The cavity in the draw-head inwhich the tumbler B is seated is so formed that the hook b may restagainst its front sides c for a support. D is a lever, pivoted at e inthe-upper side ot the draw-head, and its lower end vformed into teeth d,which engage with the teeth b" of the tumbler B.

The upper end of the lever D is weighted or gravity until the link E,entering, strikes the upper part of the tumbler B, and propels itbackward to the coupled position. (Shownby dotted lines at same figure,and by full lines` at Fig. 3.) The weighted lever D will now hold theparts in their new position by gravity, also, until, by hand or somedevice extending from any desired part of the car, the lever4 D isthrown back and uncoupling effected.

The flexibility of the tumbler B will always insure support against theshoulder c, and the joint for producing ieXibility also permits ofchanging the points of the tumbler, and of making them of any metaldesired, and different from the metal of which the body is composed.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, isl l. The tumbler B, constructed, asdescribed, with an enlarged upper end, b', provided with teeth b, andarranged to operate with the correspondingly-toothed lever D, draw-headA, and link E, substantially as and for ther purpose'speciied.

2. The oscillating tumbler B, constructed in two parts, b 11', hinged toeach other, and arranged to operate with the draw-head A and link E,substantially as and for the purpose specified. 1

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.
